With the outstanding side opposite sides from panel 8 on locking bolt 10 be formed with a bearing 32a, the part of a tabular tang 33 cooperates with this bearing 32a.

Locking bolt 10 links to each other with tabular tang 33, so the stroke coupling that the motion of tang is increased by one of this locking bolt.Tang 33 is guided along glide direction by a pair of pin that cooperates with the groove 36 (and seeing Fig. 4) of this tang 34,35, this tang is positioned at bearing 32a inside, and it is fixed with the diapire 1 of lock housing by a square pin 37 and cooperates with a groove 38 that is positioned at the tang portion in the locking bolt outside slidably.

As Fig. 4 more clearly shown in, tang 33 and locking bolt 10 intersects by two pins 39,39a; First pin 39 is connected with tang rigidly and the groove 40 that in bearing 32a, forms in the second pin 39a that slides then be connected with locking bolt 41 rigidly and slip in the groove 41 of tang.

Pin 39, the groove connector 42 that is formed in the connecting rod 43 of 39a and cooperate, and this connecting rod is supported to it can be swung around a pivot 44 that is fixed on the diapire 1 of lock housing.One spring 45 is arranged between tang 33 and the rear wall 4 to help locking bolt 10 outwards to move from lock housing.

The effect of connecting rod 43 is the elements that are used to increase the locking bolt stroke as.In fact, connecting rod 43 is with respect to the ratio between the brachium of pivot 44 stroke of tang 33 to be converted to the increase stroke of locking bolt by pin 39,39a, so cause locking bolt to increase and deeper penetrate in ccontaining its selvage from panel 8 is outstanding.Square pin 37 also prevents the element that locking bolt slides as one outside the guide as tang 33.

As Fig. 3 more clearly shown in, 46 cooperations of the tooth of a square pin 37 and a tabular pawl 47, this tabular pawl be roughly C shape and by two wing plates 48,49 with respect to the cooperation of the groove 50,51 of tang and along being directed with the rectangular direction B of direction A.This wing plate 48,49 is connected pawl 47 along direction A rigidly with tang 33, this tang correspondingly makes this pawl movement therewith when it moves.

Pawl 47 is driven by a spring 52, and wherein an end leans the adjustment sheet of tang and the other end acts on the wing plate 49, so thereby tooth 46 is remained on one is used for the position that blocking pin 37 stops tang 33 and locking bolt 10.

For locking bolt 10 is unclamped, by lever 27 driving claws 47, or by existing key operation cylinder 53, this cylinder is suitable for being contained in the bearing of lock housing and acts on by its lug 55 on the wing plate 48 of pawl when lever operated.

Lever 27 acts on the pawl 47 by a pallet 56, and this pallet pivots on tang 33 by a pivot 57.

Pallet 56 comprises two arms 58,59 that are configured to L shaped structure.And an adjustment sheet 60 is set betwixt, this adjustment sheet forms the hole 61 that a wing plate 49 cooperates therein with arm 59.The triangle adjustment sheet 31 of lever 27 acts on the arm 58 and pallet 56 is rotated, thereby arm 59 is acted on the wing plate 49, and thereby pawl 47 is elevated to a level, at this place, tooth 46 can make square pin 37 slide in groove 38.

Tang 33 also is equiped with in the groove 63 that can form the transverse bolt 62 that slides in a connecting rod 64, this connecting rod is movable joint at the end place to the lug 66 of wheel hub 22 by pivot 65.Be positioned at connecting rod 64 ends relative with pivot 65 and have a flat site 67, when locking bolt 10 was positioned at the position of indentation lock housing, this zone was in the actuating range of lug 55, so can make the chain shot action by making cylinder 53 actions.

As mentioned above as seen, in order to unblank with handle, state (position shown in Figure 4) from chain shot 9 and all its corresponding selvage cooperation of locking bolt 10, the be rotatably connected rotation of wheel hub 22 thereon of handle has determined the withdrawal of chain shot 9 by finger 21, simultaneously, by the cooperation of tooth 29 on lug 30, determined the rotation of lever 27.Its triangle adjustment sheet 31 rotates pallet 56 by acting on the arm 58, so thereby raise with wing plate 49 and with pawl 33.Moving upward of pawl 33 unclamped square pin 37 and supported wing plate 49 engagement arm 32, pushes it against rear wall 4 and mobile simultaneously tang 33 and locking bolt 10.

According to basic characteristics of the present invention, lock can be when chain shot cooperates in the corresponding selvage at the reveal wall with locking bolt 10 from movingly.In practice, this need not operating crank or cylinder 53, and only needs by utilizing the withdrawal of being undertaken by chain shot 9 simply and giving prominence to motion, at first by impact sidewall when door is closed, cooperates with corresponding selvage under the thrust of spring 20 then.

For this purpose, lock comprises a sensor, is used for the fastening position of the door that is made of an auxiliary chain shot 69 (seeing Fig. 1 and 2) that is equiped with a flange 69 that can slide at the opening of panel 8 is detected.

One bar 70 is inner outstanding to lock housing from this auxiliary chain shot 68, and this auxiliary chain shot chamfering before chain shot 9 has can be retracted into lock housing when impacting sidewall with box lunch.Bar 70 is directed in a cross-piece 71 that is enclosed between diapire 1 and the cover cap 6.

One support 72 is fixed on the bar 70 and is equiped with two wing plates 73,74 near flange 69 and this boom end.One bridging piece 75 is between wing plate 73,74 and be parallel to bar 70; One chamfering 76 is formed on the edge of described bridging piece and forms an elevated portion 77.One spring 78a is configured on the bar 70 and action between cross-piece 71 and wing plate 73, correspondingly will assist chain shot 68 to extrapolation.

One slide mass 78 is configured in support 70 tops and is made of a plate that is provided with the groove 79,80 that direction that a pair of edge is parallel to direction A extends.Corresponding pin 81,82 cooperates in groove 79,80, and is outstanding and along direction A guided slidable body 78 from diapire 1.

One L shaped lever 84 is connected on the slide mass 78 with a rocking bar mode movable joint by a pivot 83, and have one downwards towards and act on the first arm 85 that a spring 86 is arranged it on.When auxiliary chain shot 68 was positioned at panel 8 outsides, described spring made the end of arm 85 keep leaning on the elevated portion 77 of support 76, and when auxiliary chain shot was retracted into lock housing, spring 86 made arm 85 keep leaning on the pillar 86a of slide mass 78.Lever 84 has one from second arm 87 of pivot 83 to rear wall 4 extensions; When arm 85 leaned on pillar 86a, described arm 87 was outstanding from the upper limb of slide mass 78 in a position, offsets with the wing plate 13 with support 15.

By a pivot 88 pallet 89 is pivoted on slide mass 78, and be provided with the elevated portion 90 on a formation one inclined-plane 91.One spring 92 is on pivot 88, and the opposite end of described spring leans against elevated portion 90 belows and is lower than the adjustment sheet 93 of slide mass 78, so that pallet 89 stops slide mass towards pillar 94 motions, thereby inclined-plane 91 is tilted with respect to glide direction A.

Inclined-plane 91 by one below plate 96 (see figure 1)s that are positioned at lever 84, bar 70 and pallet 89 tops outstanding pin 95 cooperate.

Plate 96 has two grooves 97,98 that are parallel to direction B, and the guide finger 81 and that wherein is combined with slide mass 78 is connected to the other pin 99 of the diapire of lock housing rigidly.

The lower end of plate 96 has a step 100 and a projection 102, and this step is suitable for offseting with an edge 101 of tang 33, and effect has an end of a spring 103 on this projection.Spring 103 is on a pillar 104, and this pillar is connected rigidly with diapire 1, and its opposite end leans on pin 99.Spring 103 make plate 96 one wherein step 100 confession that leans the edge 101 of tang 33 stop on the position of tang 33 towards locking bolt 10 motions.

The motion of locking bolt 10 takes place simultaneously with chain shot during closing the door, and is as described below.

When door was opened, lock was in state shown in Figure 1, and wherein chain shot 9 and auxiliary chain shot 68 are outstanding from panel 8, and locking bolt 10 is positioned at lock inside.Because strength ratio spring 86 height of spring 78a, auxiliary chain shot 68 is blocked and leans on plate 8 by spring 78a, and the arm 85 of lever 84 then is blocked and leans on the elevated portion 77 of support 72.Second arm 87 of lever 84 is towards level and do not offset with the lower end of wing plate 13.The action of the spring 86 on the lever 84 remains on a blocking position by the decision of the bearing of the pin in the groove 79,80 81,82 with slide mass 78.Locking bolt 10 is by being blocked in the lock housing inboard by cooperating with edge 101 with the step 100 of the plate 96 of tang 33 locking.

When door is closed, in the lock housing that chain shot 9 contacts with sidewall with auxiliary chain shot 68 and retraction is locked.The withdrawal stroke of auxiliary chain shot 68 can make lever 84 rotate and make arm 87 correspondingly take a position, and on this position, in case wing plate moves to the outside of arm 87 ends, it promptly offsets with wing plate 13.

When chain shot 9 with the reveal wall in corresponding selvage on time, by spring 20 once more with it to extrapolation.Because auxiliary chain shot 68 does not have corresponding selvage, so still in the lock housing inboard.

By outwards moving of chain shot 9, wing plate 13 leans the end at arm 87, slide mass 78 is moved and pivot 95 cooperates with the inclined-plane 91 of pallet 89 towards panel 8, thereby plate 96 is raise along direction B towards upper wall 2 with the return action that applies by spring 103.

This motion causes the projection disengagement of edge 101 with the panel of the locking bolt 10 that is subjected to spring 45 pushings of step 100 and tang 33.

Be locked in this point and be in transition state shown in Figure 4, wherein sell 95 and moved to 91 outsides, inclined-plane.

At this some place, by spring 103 plate 96 is drawn in a position downwards, plate leans at the back of tang 33 in this position, in case and locking bolt withdrawal promptly prepare to cooperate with edge 101 and reset by step 100.

For lock is opened, can act on handle is on the wheel hub 22, or by cylinder 53.

Under first kind of situation, as mentioned above, system causes chain shot 9 withdrawals by finger 21, makes the locking bolt withdrawal by lever 27 simultaneously, and these leverage act on the tang of the locking bolt that has extension 32 by wing plate 49 unclamp pawl 47 by triangle adjustment sheet 31 and pallet 56 after.

Under second kind of situation, locking bolt is the motion withdrawal by being produced by lug 55 at first, this lug is moving pawl 47 risings with tang 33 with after unclamping square pin 37 by first commentaries on classics towards rear wall 4, transfer to by second then and be used on the connecting rod 64, this connecting rod makes chain shot 9 get back to retracted position by wheel hub 22 and lever 21.
